Tomatoes and tomato products are rich sources of carotenoids-principally lycopene, followed by β-carotene and lutein. The aim of this work was to study the effect of heat treatment on carotenoid content in cherry tomatoes. Raw and canned products were sampled and analysed; furthermore whole, skin and pulp fractions of cherry tomatoes were analysed when raw and home-processed, in order to better...

The carotenoid content of fresh, commercially canned and frozen samples of two cultivars, White Shoepeg (WS) and Golden Whole Kernel (GWK) corn (Zea mays), from the same production field was studied. WS and GWK corn samples were harvested daily over a five-day-period and randomly selected for analysis as fresh, frozen or canned. Major carotenoids detected were lutein and zeaxanthin, and to a le...

BACKGROUND Prenatal bisphenol A (BPA) exposure may be associated with developmental toxicity, but few studies have examined the variability and predictors of urinary BPA concentrations during pregnancy. OBJECTIVE Our goal was to estimate the variability and predictors of serial urinary BPA concentrations taken during pregnancy. METHODS We measured BPA concentrations during pregnancy and at ...

To be able to fulfil high market expectations for a number of practical applications, Environmental Product Declarations (EPDs) have to meet and comply with specific and strict methodological prerequisites. These expectations include the possibility to add up Life Cycle Assessment (LCA)-based information in the supply chain and to compare different EPDs. To achieve this goal, common and harmoni...

The objective of this study was to better understand the effect of butter composition and emulsion structure on growth and survival of Clostridium sporogenes, used as a surrogate for C. botulinum in canned butter. The lack of a thermal process step in commercially available canned butter raises questions of potential safety, because it is hermetically sealed and generally exhibits anaerobic gro...
